AMS and Shell Energy will work together to identify new and existing direct access and utility customers who want to install advanced battery systems.

AMS will design, finance, build and operate the projects. Shell Energy will have dispatch rights on capacity for use in planning and market operations.

This new agreement comes on the heels of a 500-MWh storage deal between AMS and Tesla as well as a contract signed in November 2014 with Southern California Edison (SCE) to build 50 MWs of storage in buildings to provide grid support.
